Photos 1-4 from Rimmer de Vries show the process for Resnova megaphylla. He recommends to "take cuttings early in the season from large leaves". For more details see his PBS list post. Photo 5 from Colin Davis shows the results for Lachenalia quadricolor and photo 6 from Pamela Slate for Lachenalia viridiflora.

This wiki article is based wholly on the PBS list post Leaf Cuttings for Eucomis Props by PBS member Robert Lauf (Tue, 18 May 2021.)
Robert explains that the following is the propagation method of choice for his new Eucomis releases: "Allow me to summarize a few tidbits from personal experience." This is his post, in his words:
Note that I prefer the dip solution over Clonex gel, but both can work OK. Some growers don't use hormone at all and it seems to work. Clonex is my weapon of choice for woody plant cuttings.
Lately I have tended to use the little leaves at the top of the inflorescence (the "pineapple" so to speak) rather than slices off the main leaves, for several reasons:
The most important things are good hydration of the plant ahead of time, and a really sharp blade. Then, keeping an eye on humidity and avoiding rot.
